The subject of this invention is a pressure gas producer and consists substantially in the arrangement of devices. which, when used singly or combined with each other in. different ways, considerably increase the tional area of the producer, on the other hand for breaking up the slag and finally makes it possible for the fuel to be placed in the producer. in a peculiar'and regulable manner, so that the combustion and vaporizing zoneof the fuel can be placed at different levels in the shaft of the producer. Hence, in practice according to the kind of fuel used and the kind of gas to be produced, the choice of one or other of the devices referred Fto above or a suitable combination of the same will suggest itself.

In the accompanying drawings differentconstructional examples of the invention are shown:

Fig. 1 is a'longitudinal section through the gas producer,

Fig. 2 is a cross-section on line 00-00 of Fig 1,

Fig. 3 is a longitudinal section through a second constructional form of the producer,

Fig. 4.shows the distributing member for the latter on an enlarged scale in vertical section,

Fig. 5 is a longitudinal section of a constructional form of the distributing member and Y Fig. 6 is a cross-section on of Fig. 5.

The gas producer comprises a shaft 1, the immcrsible ring, 2 of which is immersed in the rotating ash vessel '3, which is filled with water and moves the slag and ash, as they the line 66 emerge, against the lateral scraper 4, along which the slag and ash are carried away.

The blast distributing member is preferably given a cylindrical shape and consists of separate rings 11 lying one above the other, between which are ribs or the like, so that circumferential slits are left.

This arrangement does not only provide the advantage of an increased ash space, such as described above, but a distributing 'member of this kind may be built up of exactly similar interchangeable separate parts. The height of the distributing member in one and the same producer may be readilydetermined according to the kind of fuel used. 7

It is only necessary to use a greater or smaller number of such .rings 11 in building up the distributing member, so as to obtain an ash space of the size required for the'complete using up of the fuel.

The distributing member is covered by a cap '12. The fuel and the ash are supported by the ash pan 3. By this way ofbuilding up the distribut-' ving member constructional forms may be obtaincd, with which it is possible to regulate the inflow of the mixture of steam-and air into the producer in such a manner that the actual incandescent and combustion zone can be placed in a suitable position for the conditions of operation. The outlet. apertures for the mixture of gas and air may be made in the form of nozzles, whereby the 'distributing member becomes a nozzle chamber.

-According to Figs. 3 and 4 the rings 11 have radially directed nozzle apertures 13 and the cap 12 may be provided with such nozzle openings 14. Into the nozzle chamber formed by the built up rings a hollow cylin-- drical sliding member 15 is inserted, the wall of which is provided with perforations 16. The mixture of steam and air entering the cylindrical member 15 passes through the perforations 16 and the nozzle 13 into the producer. By sliding the cylindrical member the relative positions of the perforations 16 and of the nozzles 13 may be varied. Thus, the incandescent or combustion zone, two extreme vpositions of which 17 and 18 are shown in the drawing, will be a portion of a paraboloid, which is substantially determined by the flow of steam and air mixture emergng from the lowest nozzl'e. Hence, in one and'the same producer with one and the samefuel the incandescent or combustion zone. may be kept at difi'erent levels and may be lowered to such an extent that in the charging space in the producer lying above the combustion zone there will be a distillation of the material. In many cases it will thus be unnecessary to provide a separate retort.

If the combustion zone does not extend right up to the wall of the producer and if in this case only the curve 19 determined by the gases formed extends as far as the; producer wall so, that unburnt' fuel passes through, it will only be necessary to depress the paraboloid, as shown by the curve 18, by regulating the supply of steam and air. By this means the incandescent zone is placed lower and will extend to the wall of the gas producer, so that the whole of the charging and distilling shaft is cut oil over its entire cross-sectional area from the incandescent or combustion zone.

This manner of regulation does not entail any change in the quantity admitted. The variation in the paraboloid of flow is effected solely by regulating the effective cross-sec tional area of the outlets of the nozzles.

In Figs 5 and (r the nozzle body 20 is made in one piece. In the wall of the nozzle body axial chambers 21 are provided, which are separated from the nozzle apertures proper 13 and from one another. The chambers 21 communicate at the top with the hollow space in the cap 12, into which the mixture of steam and air .is admitted in the direction shown by the arrow 22. The cylindrical sliding member 23, which is inserted in the nozzle body, is closed in the present instance. The direction of flow of the mixture of steam and air is reversed in the cap 12 and only then passes into the: producer through the nozzle aperatures 13. In this arrangement the nozzle body is also cooled by the mixture of steam and air.

According to the invention means are also provided for causing the ashes and slag to pass freely within the producer over the cm tire cross-sectional area of the same and, more particularly for causing the slag to be broken up.

For this purpose, as will be seen from Figs. 1 and 2, the cutters or the like 24 are caused to coac-t with the shearing members 25 on the immersed ring 2, which members check the motion of the slag. The shearing members 25 are distributed uniformly right around the producer. The lateral scraper 4 and the shearing members 25 do not extend down to the bottom of the ash tray, so that 'a layer of slag of a definite height can accumulate at the bottom of the said tray, which provides a constant stationary resistance for the removal of the slag and ash.

This has the advantage, that the incandescent zone remains uniformly in one and the same position, whereby the yield of the producer is considerably increased. The millers or cutters 24 together with the motionchecking and shearing members 25 form a device for breaking up the slag into pieces of a fair size, which rest against the shearing members and are broken off or .broken up by the cutters 24, which move with the rotating ash pan. This at the same time imparts .a lateral movement to the pieces of slag, so that the actual shearing pressure is reduced. W

In any cgse, in allfproducers, whether provided witi an ordinary grate or with a distributing body for the mixture of steam and air, as described above, there will be a stabilizing of the combustion or incandescent zone and in addition to this a free passage for the ash and slag through the producer, since the devices for breaking up the slag are no longer in the interior of the producer, but are located outside the same.

By a special way of regulating the charging of the fuel into the producer, provision may be made for variations in the position of the combustion or distillation zone, as may be found necessary owing to the fuel differing in quality or in its size. A charging pipe, which may be varied in length and extends into the producer, may be used for this purpose.

According to Fig. 1 the charging pipe 2 is combined with a pipe 27, which slidc's on it.

By adjusting means operated from outside the producer the pipe 27 may be caused to extend to a greater or less extent beyond the end of the pipe 26, 'so that different charging heights 28, 29, are obtained for the varying positions of the combustion zones.

By adjusting the position of the pipe 27 the pipe is connected to one or more bars 30, having a series of holes 31, into which pins or the like 32 can be inserted, which abut against the feet of the charging device.

According to whether the arrangements described are to be employed inconncction with existing producers or embodied in new producers, one of the arrangements de scribed above is used or a combination of the same as required by the operating conditions in each case.
